Plug-in solar panels became legal in the UK today (August 27). These panels plug directly into an ordinary mains power socket, and could cut your electricity bill considerably; in fact, experts have told us that a plug-in solar system could effectively pay for itself in three to five years.
However, although plug-in solar panels are now legal, you can't yet connect a battery that stores electricity then discharges it back into the circuit later directly to a wall socket.
